\paragraph{Description}\label{description}

We recommend that you keep the IRIS root directory on the permanent
Matlab search path. Each time you wish to start working with IRIS, you
run \texttt{irisstartup} form the command line. At the end of the
session, you can run \href{config/irisfinish}{\texttt{irisfinish}} to
remove IRIS subfolders from the temporary Matlab search path, and to
clear persistent variables in some of the backend functions.

The \href{config/irisstartup}{\texttt{irisstartup}} performs the
following steps:

\begin{itemize}
\item
  Adds necessary IRIS subdirectories to the temporary Matlab search
  path.
\item
  Removes redundant IRIS folders (e.g.~other or older installations)
  from the Matlab search path.
\item
  Resets IRIS configuration options to default, updates the location of
  TeX/LaTeX executables, and calls
  \href{config/irisuserconfighelp}{\texttt{irisuserconfig}} to modify
  the configuration option.
\item
  Associates the default IRIS extensions with the Matlab Editor. If they
  had not been associated before, Matlab must be re-started for the
  association to take effect.
\item
  Prints an introductory message on the screen unless
  \texttt{irisstartup} is called with the \texttt{-shutup} input
  argument.
\end{itemize}
